Offering description										the Company offered 22,500,000 ordinary shares, par value US$0.0001 per share at a purchase price of US$0.30 per share. The Company also offered 177,500,000 pre-funded warrants to purchase 177,500,000 ordinary shares, exercisable at an exercise price of $0.0001 per share (the “Pre-funded Warrants”, each a “Pre-funded Warrant”), to those purchasers whose purchase of ordinary shares in the offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the holder, 9.99%) of the Company’s outstanding ordinary shares immediately following the consummation of the offering. The purchase price of each Pre-funded Warrant is $0.2999, which equals the price per ordinary share being sold to the public in that offering, minus $0.0001. The Pre-funded Warrants became immediately exercisable upon issuance and may be exercised at any time until all of the Pre-funded Warrants are exercised in full.
Reverse Split description										the Company became exercisable for 1/30 ordinary share of the Company, and the exercise price of Company’s outstanding warrants was increased to US$9.00, adjusted from $0.30 prior to the Reverse Split and representing the temporarily reduced price based on the Company’s Tender Offer Statement on Schedule TO, as amended and supplemented, originally filed by the Company with the U.S. Securities and Exchange Commission on December 7, 2020 (the “Tender Offer”). Based on the terms of the Tender Offer, following the date on which the closing price of the Company’s ordinary shares has been equal to or greater than $90.00 per share for at least twenty (20) trading days during the preceding thirty (30) trading day period, the exercise price of the Company’s outstanding warrants would be increased to US$345.00.
Ordinary shares description										the Company offered 22,899,047 ordinary shares, par value US$0.003 per share, consisting of (a) 1,470,475 ordinary shares issuable upon the exercise of pre-funded warrants (the “Pre-Funded Warrants”) and (b) 21,428,572 ordinary shares issuable upon the exercise of investor warrants (the “Investor Warrants”). Each Pre-Funded Warrant is exercisable for $0.001 per ordinary share and may be exercised at any time until all the Pre-Funded Warrants are exercised in full; and each Investor Warrant has an exercise price of $0.70 per share, is exercisable on or after August 8, 2022 and will expire on August 9, 2027.
